With tooth brushes currently in use, the tooth paste is squeezed out ofa tube and spread over the bristles of the tooth brush. After use thetooth brush is put back into a separate container so as to keep it cleanand free from contamination. To perform the said operations, quite anumber of parts have to be handled, viz, the tooth brush itself, thetube of tooth paste and the container. Thus, apart from the physicaleffort, time is wasted both in washing the teeth'and in maintaining thetooth brush in good condition. Additionally, having so many parts, moreroom is taken up. The purpose of this invention is to enable themanufacture of a tooth brush combined with a container to also serve asa dispenser for spreading the tooth paste onto the tooth brush. The saidtooth brush is able to lock onto the upper part of the said containerand, in this locked position, to cause the paste to be spread over itsbristles.

Another purpose is for the tooth paste, which is contained in a specialdispenser, to be pushed into the tooth brush by means of externallyoperated controls and to go through perforations leading into thebristles of the tooth brush. Yet another purpose is for thecontainer/dispenser to serve, in the open position, as the handle of thetooth brush, since the latter is jointed or hinged on to the container.

Other purposes and advantages can be seen from the following descriptionand from the enclosed table which shows a schematic example of one wayin which the invention can be used.

FIG. 1 on the a/m table provides a cutaway view of the device in theclosed position.

FIG. 2 instead shows the device ready to be used. The container 1 whichis shaped in such a way that it fits easily into the palm of the hand,has the tooth brush 2 hinged or jointed onto it 11 and when not in use,the brush is stored away inside the container, thereby serving as itscover.

The tooth paste dispenser 5 is filled through an aperture 4 which, oncethe filling operation has been completed, is sealed by means of a plug 3or by some other suitable stopper. With the rotation in one direction ofthe external control 8 which is cast integral with the threaded spindle6, the part 7 moves inside the dispenser and pushes the tooth pastealong until some goes through the holes 10 and penetrates sufficientlyin between the bristles of the tooth brush 2 which is thus now ready foruse and is opened up as per FIG. 2.

Obviously when the tooth paste has been completely used up, a reverserotation of 8 causes the pusher 7 to return to the position shown andthis prepares the dispenser 5 ready for filling again.

The mechanism for moving the tooth paste can be made in various ways,suitable for the purpose, and

these may differ from the examples given.

The tooth brush and the container should both be made, out ofpreference, of a light resistant plastic material, such as syntheticresin, nylon or some other suitable material.

It is understood that the invention described herein schematically andpurely as an example, also covers variants which, as such, can be takenas referring to one and the same device.

I claim:

1. A combination toothbrush and toothpaste dispenser, comprising atoothpaste dispenser,

a toothbrush pivotally connected to an end of said dispenser andpivotable to an extended position with a brush portion away from saiddispenser, as well as to a closed position with said brush portionpositioned abutting a dispensing portion of said dispenser,

said dispenser being hollow and having a substantially cylindricalhollow portion, and having at least one filling opening adapted forfilling the paste therethrough into said dispenser,

1 a removable plug for closing said at least one filling opening,

said dispensing portion being formed with a plurality of projectionswhich project into said brush portion when said toothbrush is in saidclosed position, and each of said projections having an orificetherethrough communicating with the hollow interior of said dispenser,

a threaded spindle extending axially through said cylindrical hollowportion and rotatably mounted at its both ends in said dispenser,

a disc threadably axially movable disposed on said spindle and having anouter periphery substantially equal to the inner periphery of saidcylindrical hollow portion,

an external rotatable control knob means disposed at said end of saiddispenser connected to said spindle for rotating said spindle, wherebytoothpaste in said dispenser is pushed by said disc through saidorifices said dispenser adjacent said dispensing portion is recessshaped, complementary to said toothbrush portion and that saidtoothbrush in said closed position substantially follows the outercontour of said dispenser, and

said dispensing portion is angularly inclined relative to the axis ofsaid cylindrical hollow portion such that said dispenser narrows with anarrowing of its hollow interior toward the remote other end of saiddispenser.

2. The combination toothbrush and toothpaste dispenser, as set forth inclaim 1, wherein said orifices are formed with increasing diameters atcloser positions approaching said remote other end of said dispenser.
